我正在尝试使用ROME API解析原子提要以提取提要。原子提要给了我内容属性，其中包含文章的图像和描述。 这是原子饲料的网址：https://news.google.com/news/section?output=atom&ned=in&q=narendra%20modi。 现在我想从内容部分中提取图像和描述。

但它什么也没有回报。另外我不知道如何继续提取描述：
Elements img = doc.getElementsByTag("img");
for (Element el : img) {
System.out.println("Image Found!");
System.out.println("src attribute is : "+el.attr("src"));
}
请帮助我。
答案 0 :(得分：0)
试试这段代码。请注意，RSS源是直接使用Jsoup获取的。
Document news = Jsoup.connect("http://news.google.com/news/section?output=atom&ned=in&q=narendra%20modi").get();
int i=0;
for (Element entryContent : news.select("entry > content")) {
System.out.format("\n## ENTRY %d\n", ++i);
for (Element el : Jsoup.parse(entryContent.text()).select("img[src], tr td.j font[size]:nth-of-type(2)")) {
String elementTagName = el.tagName();
if (elementTagName.equalsIgnoreCase("img")) {
System.out.println("src attribute is : " + el.attr("src"));
} else if (elementTagName.equalsIgnoreCase("font")) {
System.out.println("description is : " + el.text());
} else {
System.out.println("Unexpected element >> " + el.html());
}
}
}
